What does Huang Yanmeng's poem mean?

Throughout the ages, it has been a long-cherished dream of China people to fly away from the earth and travel in space. In ancient China, there were legends such as "the Goddess Chang'e flying to the moon", "Jade Rabbit tinkering with medicine", "Kunpeng spreading her wings" and "Nine days on the moon". With their passion and extraordinary imagination, the people of China simply carved a magnificent dream of flying in the sky. This poem expresses the author's views on Shenzhou 5.
